This document specifies test methods for the determination of geometrical characteristics of modular mechanical locked floor covering panels in respect of thickness, length, width, squareness, straightness, width flatness, length flatness, openings between assembled elements and height differences between assembled elements.

The geometrical characteristics of modular mechanical locked panels are important considerations because installed flooring will have an objectionable appearance if these performance criteria are not followed. This can cause the installed panels to line up unevenly, producing unsightly seams, uneven surfaces and corners that do not match.
